    Nice!
    I use to take mine to 14.5 and they would settle at 13.6. That's when I get the full 14Ah out of them.

    Wow, you took that primary below 11V almost to 10V...
    Have you decided on a run time or are you aiming for a particular voltage?
    I love your generator winding to feed you cap dumper - sweet!

    Here is a run I just did on some 20AH lifePO4 batteries.

    This was a gen mode cap dump run AKA,,mode3 as shown by Mr. Bedini a few years ago on the conference video. The dump board is of my own design and does not do any comparator functions. I just adjust my dumps to the input to achieve my desired voltage/current.

    Here is a video I shot throughout the run. Something happened to the sound on the last section.

    Thanks Patrick. I am still trying different runs on these. As I was saying in the video I am pretty sure I am asking too much out of those little batteries to supply around 1.5A for so long. They can handle that and more for short periods but I don't think it is the best idea for prolonged runs.

    I think I might try taking one of those 33kuf caps off and run the machine at lower draw like 700ma or so. I can play with the timing on the dump and the capacitor size to try and keep it at 24v or somewhere close. The setting I was using on that run is basically what I use on large deep cells, it did ok but I think I could do better with some adjustment.

    I will post another run after I tweak it a bit more.

    *EDIT*
    Realized I didn't really answer your question. On this run I was just trying one on the front and one on the back to see what would happen. I was just running it till the primary drained or the back got charged.

    Yea I brought it down to 10.23v, phone rang and whoops I let it go a bit longer.

    I am setting up a gen run right now. I am taking the cap dump off and will sort of be going a different direction. I am going to hammer the hell out of it. These things really seem to love the current so I am going to give it a steady drink and see. This timeI will put a more reasonable primary on. I know it's better to have a large primary but I still like to put equals on once and awhile to see how they do.

    This could help under low light situations, add some txt to change the freq as the clouds come in etc...

    I am a little late to this thread. I used one of those voltage sensors in a questionable cap dump circuit I used for testing my SS SSG. Worked pretty well.



    You can see the sensor on the breadboard.
